Steps: Factor The Expression
2xz-3yz+8x-12y

Factor out z from the first 2 terms.
z*(2x-3y)+8x-12y.

Factor out 4 from the last 2 terms.
GCF of 8 and 12 is 4.
z*(2x-3y)+4(2x-3y)

Factor out 2x- 3y from the
expression.

(2x-3y)*(z+4)

Final Answer: (2x-3y)*(z+4)

5 Michiko has a metal container in the shape of a cuboid. The container is 2.4 m long, 1.2 m wide and 0.6 m high. Michiko plans

konstantin123 [22]

Answer:

a) Michiko needs to buy 18 tins of paint.

b) cost of paint would be $152.82

Step-by-step explanation:

Surface area of cuboid = 2lw + 2lh + 2hw

Length (l) = 2.4 m

Width (w) = 1.2 m

Height (h) = 0.6 m

SF = 2(2.4 × 1.2) + 2(2.4 × 0.6) + 2(0.6 × 1.2)

= 5.76 + 2.88 + 1.44

= 10.08 meter²

Paint coverage is 4.5 meter² per liter.

Total paint used in one coat =

= 2.24 liters

Paint used in double coats = 2.24 × 2 = 4.48 liters

a) Size of one tin paint = 250 ml

1 liters = 1000 ml

4.48 liters = 4.48 × 1000 = 4480 ml

Number of tins needed by Michiko =

= 17.92 ≈ 18 tins

b) Cost of one tin of metal paint = $8.49

∴ cost of 18 tins of paint = $152.82

a) Michiko needs to buy 18 tins of paint.

b) cost of paint would be $152.82

Craig has a rectengular deck that measures 799 inches and 245 inches premeter and if the addtional deck is 33 inches longer,what

melomori [17]

Answer:

The length of the lights is 2088 inches

Step-by-step explanation:

<em>The question is mixed up with another (See comment for correct question)</em>

Given

$Length = 799in$

$Width = 245in$

Required

The perimeter of the deck (this is what the question implies)

The perimeter (P) is:

$P = 2 * (Length + Width)$

$P = 2 * (799 + 245)$

$P = 2 * 1044$

$P = 2088$
